Functional electrical therapy: retraining grasping in spinal cord injury

Area of Science:

• Neurorehabilitation
• Biomedical Engineering
• Physical Medicine and Rehabilitation

Background:

• Quadriplegia significantly impairs grasping function, impacting independence.
• Restoring hand function is a critical goal in spinal cord injury rehabilitation.
• Current rehabilitation methods for grasping function in quadriplegia have limitations.

Purpose of the Study:

• To evaluate the clinical efficacy of functional electrical therapy (FIST) for improving grasping function in individuals with quadriplegia.
• To assess the feasibility of implementing FIST by occupational therapists in a clinical setting.
• To explore patient perceptions of FIST.

Main Methods:

• A randomized controlled trial involving 21 participants with spinal cord injuries (C3-C7).
• Intervention group received functional electrical therapy (repetitive grasping exercises with neuroprosthesis and electrical stimulation).
• Outcome measures included FIM, SCIM, hand function tests, and qualitative interviews.

Main Results:

• Observed differences between groups, though not statistically significant due to small sample size.
• Positive consumer perceptions regarding Activities of Daily Living and self-satisfaction.
• Functional electrical therapy was implementable by occupational therapists.

Conclusions:

• Functional electrical therapy demonstrates potential as an effective treatment for restoring grasping function in quadriplegia.
• Further research with larger sample sizes is necessary to establish statistical significance and optimal participant selection criteria.
• Occupational therapists can integrate functional electrical therapy into clinical practice for spinal cord injury rehabilitation.
